Logging In to the MM910 CLI

Logging In to the MM910 CLI

You can log in to the MM910 command-line interface (CLI) over Secure Shell (SSH) or a serial port.

Scenarios

Log in to the MM910 CLI in either of the following ways:

  • Over SSH: Remotely log in to the MM910 CLI over an Ethernet. You do not need to reconnect the network cable when switching between the active and standby MM910 CLIs.
  • Over a serial port: Directly connect to the MM910 by using a serial cable to log in to the CLI, without using an IP address.
NOTE:
  • If the number of consecutive attempts to log in to the MM910 CLI and web user interface (WebUI) with wrong passwords reaches 5, the account is locked. The account is automatically unlocked in 10 minutes. After the account is unlocked, enter the correct password to log in. If you attempt to enter a password again within 10 minutes, the lock duration is reset to 10 minutes no matter whether the password is correct.
  • An account can log in to the MM910 CLI or WebUI only through one IP address at a time. If an account is logged in and then logs in through another IP address, the account will be logged out.
  • After logging in to the MM910 CLI or WebUI, you are logged out of the management UI if you do not perform any operation within a specified time period. The default lockout duration of the CLI is 2 minutes and that of the WebUI is 5 minutes. You can change the values as required.
  • The MM910 supports a maximum of 32 clients to log in to the WebUI and 100 clients to log in to the CLI at the same time.
  • For details about the operations on the WebUI, see the Online Help.

Prerequisites

Conditions

The MM910 is powered on.

Data

Table 5-1 lists the default data required for logging in to the MM910 CLI.

Table 5-1 Default data

Data

Default Value

Default user name and password

  • User name: root
  • Initial password: Huawei12#$

Static IP addresses and subnet masks of the active and standby MM910s

A fixed IP address of an MM. This IP address can be used to log in to the command-line interface (CLI) or web user interface (WebUI) of the MM from a local PC. To query the static IP address of an MM, run the ifconfig command. The value of eth0 is the static IP address.

  • MM 1 static IP address: 192.168.2.1
  • MM 2 static IP address: 192.168.2.2
  • Subnet mask: 255.255.255.0

Floating IP address and subnet mask of the MM910

A publicly-accessible IP address that is mapped to the MMs working in active/standby mode. The floating IP address is always mapped to the active MM. To query the floating IP address, run the ifconfig command. The value of eth0:0 is the floating IP address.

  • Floating IP address: 192.168.2.3
  • Subnet mask: 255.255.255.0

Tools

  • PC with an RS232 serial port
  • DB9-RJ45 cable

Procedure

  • Log in to the MM910 CLI over SSH.
    1. Connect the local PC to the MM910.
      • Connect the network port of the local PC to the MGMT port of the active or standby MM910.

        Figure 5-4 shows the network connections.

        Figure 5-4 Network connections

        If the MGMT port on the active MM910 is already connected with a network cable, do not remove the network cable from the MGMT port. Otherwise, an active/standby switchover of the MM910s will be triggered, which may cause network interruption.

        NOTE:

        The MM910 management port is provided by either of the following modes:

        • An Ethernet port on the switch module in slot 2X or 3X.

          However, if a CX910/CX911/CX912/CX913 is in slot 2X or 3X, only a GE port can be used; if a CX920 is in slot 2X or 3X, only a 10GE port can be used. The CX910/CX911/CX912/CX913 are not recommended for providing the management port of the management module.

        • MGMT port on the MM910 panel
        • For the MM910 (U54) 2.25 or earlier, the management port is provided by the switch module by default. For the MM910 (U54) 2.26 or later, the management port is provided by the MM910 by default. For details about how to query the MM910 version, see MM910 Management Module V100R001 User Guide.
        • You can run the outportmode command to change the mode in which the MM910 management port is provided. If the switch module in slot 2X or 3X is used to provide the management port, do not connect the MM910 MGMT port and the switch module ports to the same network. Otherwise, a network storm will occur and the network will be interrupted. For details, see MM910 Management Module V100R001 Command Reference.
      • Connect the network port of the local PC to the MGMT or STACK port of the active MM910.
        • If the MGMT port of the active MM910 is available, use this port. Figure 5-5 shows the connection.
          Figure 5-5 Connection between the local PC and the active MM910 (in slot MM2 in this example)
        • If the MGMT port of the active MM910 is unavailable, connect the PC to the STACK port of the active MM910. If the STACK port is used to stack the MGMT port in another chassis, connect the PC to an idle STACK port on an active MM910 in a chassis cascaded with the E9000 chassis. Figure 5-6 shows the connection.

          If the MGMT port on the active MM910 is already connected with a network cable, do not remove the network cable from the MGMT port. Otherwise, an active/standby switchover of the MM910s will be triggered, which may cause network interruption.

    2. Log in to the MM910 CLI by using an SSH connection tool and the IP address of the active or standby MM910.

      In this document, PuTTY is used as an example during login over SSH. For details, see Logging In to the Server Over a Network Port by Using the PuTTY.

    3. Change the CLI timeout duration.

      TIMEOUT=times

      The times parameter indicates the timeout duration, in the unit of seconds. When the value is 0, the CLI never times out.

  • Log in to the MM910 CLI over a serial port.
    1. Connect the RS232 serial port on the PC to the COM port on the MM910 panel by using a DB9-RJ45 cable.
    2. Log in to the MM910 CLI by using a serial port communication tool.

      The key communication parameters are as follows:

      • Serial Line to connect to: COMn
      • Speed (baud): 115200
      • Data bits: 8
      • Stop bits: 1
      • Parity: None
      • Flow control: None
        • indicates the serial port number, and the value is an integer.

          In this document, PuTTY is used as an example during login over a serial port. For details, see Logging In to the Server Over a Serial Port by Using the PuTTY.

    3. Change the CLI timeout duration.

      TIMEOUT=times

      The times parameter indicates the timeout duration, in the unit of seconds. When the value is 0, the CLI never times out.
